Oct 30, 2017, Washington University School of Medicine/St. Louis: Early childhood adversities linked to health problems in tweens, teens https://medicine.wustl.edu/news/early-childhood-adversities-linked-health-problems-tweens-teens/ Adverse experiences in childhood — such as the death of a parent, growing up in poverty, physical or sexual abuse, or having a parent with a psychiatric illness — have been associated with physical and mental health problems later in life. But new research at Washington University School of Medicine in St. Louis has shown that multiple adverse experiences in early childhood are linked to depression and physical health problems in kids as young as 9 to 15. Further, the researchers have identified a potential pathway in the brain to explain how such stressful experiences influence poor health in kids. The researchers found that a key brain structure involved in regulating emotions and decision-making is smaller in kids who have lived through three or more adverse experiences before the age of 8, compared with kids whose lives were more stable. Young children who faced multiple adverse experiences also were 15 percent more likely to develop severe depression by their preteen and early teen years and 25 percent more likely to have physical health problems, such as asthma and gastrointestinal disorders. Due to the health problems, these kids were more likely to miss school. … “We suspect that such changes are associated with issues such as poor diet, risky and more dangerous behavior and generally not taking very good care of yourself, and overall, this contributes to poorer mental and physical health outcomes.”… The researchers found that when kids had three or more adverse experiences, they also had smaller brain volumes that, in turn, were associated with lower scores on a scale that measures how well a child expresses emotions. Poor emotional expression has been associated with depression and worse social and emotional outcomes.
